Application October 13, 1951, Serial No.251,183 4 Claims. (Cl. 257-133) This invention relates board radiator.

In the past radiators have occupied considerable floor and wall space making it dilicult to place furniture as desired. It has thus been the goal of radiator makers to reduce thesize of the radiators without detracting from the heat exchange efficiency. Recentlyv radiators have to a` new and improved base- However, in baseboard radiation the radiat a light weight baseboard radiator which is easily handled and erected to any desired length on a job site.

Another important object of this invention is the provision of a sectional baseboardradiator arranged and constructed to be readily joined one to another.

Another important object of this invention is to supply a connector means for baseboard radiator sections.

Still another object is to utilize'a baseboard radiator having a housing and integral fins with removable conduit tubing and in combination therewith a connector means for simultaneously joining adjacent sections and locking the tubing in the housing.

A still further important object of this invention resides in the self acting wedge lock connector plate usable in the joining of the several sections of a sectional baseboard radiator.

Other and further important objects and advantages will become apparent from the disclosures in the following specification and accompanying drawings.

In the drawings:

Figure 2 is a rear elevational view of a portion of the radiator sections as shown in Figure 1 and particularly the juncture between adjacent sections.

Figure 3 is a sectional view taken on the line 3 3 of Figure 2.

Figure 4 is a bottom plan view of the sectional radiator.

Figure 5 is a front elevational detail of the self locking connector plate of this invention.

As shown in the drawing:

The reference numeral indicates generally the floor of a room in which the baseboard radiator of this invention is installed. The wall of the room is designated by numeral 11 and the baseboard radiator is shown in part as sections 12 and 12a. The radiator is made in sections of any desired length. It is preferable that the sections be of such a length that they may be easily handled to facilitate shipping and moving into and around a job site preparatory to installation.

The radiator sections 12 and 12a have cast housings preferably of light weight metals such as aluminum. The housings include a front wall 13, a top 14, a transverse opening extending laterally across the front wall 13 of the radiator adjacent the top thereof, and spaced apart tns providing radiating surfaces in the exchange of heat. The spaced ns 16 are integral with the top 14 and the front wall 13 of the cast housings. The ns are spaced at regular intervals along` the length of each of the plurality of sections 12. Further the ns 16 extend from the front wall 13 to the back of the baseboard radiator whereupon they abut the wall 11 against which the radiator is mounted. It should be noted that the radiator sections 12 are spaced above the oor 10 in order that air currents may pass transversely across the radiator and upwardly from the bottom through the spaces between adjacent fins 16 and then out the transverse opening 15 for effecting quick and etlicient transfer of the heat by convection from the radiator to room atmosphere.

The fins 16 are provided with notches 17 aligned transversely adjacent the top of the radiator sections 12 and 12a. The notches 17 are opened at the rear end of the ns and the forward ends of the notches are circular in shape. Corresponding notches 18 are transversely aligned in the ns 16 at substantially midway between the top and bottom of the radiator sections. Further notches 19 are similar to the notches 17 and 18 and are transversely aligned in the tins 16 adjacent the bottom of the radiator sections 12. Each of the three series of notches 17, 18, and 19 are adapted to receive cylindrical tubing 20, 21, and 22 respectively for the purpose of conv ducting the heat transfer iluid such as hot water or steam through the radiator. The tubes 20, 21, and 22 nest firmly in the circular shaped forward ends of the notches 17, 18, and 19 wherein they make substantial contact with each of the many spaced tins 16 for transfer of the heat within the fluid medium to room air by radiation and convection as air passes through the radiator sections from bottom to top.

As best shown in Figures 2 and 4 each of the sections `12 and 12a is provided with fin end walls 23 and 24 respectively. The outer surfaces of the end Wall fins 23 and 24 are flat and when in abutting relationship the adjoining sections 12 and 12a form a continuous unit making it impossible for the casual observer to notice that there is more than one section in the baseboard radiator unit. However the inner surfaces of the end wall fins are tapered at a wedge angle for a purpose to be later described.

A connector plate 25 as best shown in Figure 5 is provided with an upwardly open notch 26, a central elongated aperture 27 and a lower elongated aperture 28. The connector plate 25 is adapted to slide over the abutting end ns 23 and 24 of the adjoining sections 12 and 12a and thereby hold the sections 12 and 12a rmly together. Although the end walls 23 and 24 have been given dierent reference characters from the ins 16 each of the end walls of the sections 12 and 12a in fact constitute an additional lin 16. The end walls 23 and 24 thus are equipped with notches 17, 18, and 19 in the same manner as the other spaced fins 16.

As best shown in Figure 4 the ns 16 have a slight taper on their side as shown at 29. Similarly the walls of the notches 17, 18, and 19 are tapered as shown at 30, 31, and 32 respectively. The connector plate 25 has the side walls of the open notch 26 tapered at a wedging angle as shown at 33 and the elongated openings 27 and 28 have their side walls tapered in a wedging angle as shown at 34 and 35 respectively. The'bottom view of the baseboard radiator unit of this invention as shown in Figure 4 discloses the connector plate 25 after it has been forcibly driven down over the abutting iin ends 23 and 24 of the sections 12 and 12a thereby holding the sections 12 and 12a against separate end-wise movement. The wedge tapered sides 33, 34, and 35 of the notch 26 and elongated openings 27 and 28 are of such a degree that they constitute a wedging taper whereby when the connector plate is drivenby force over the end walls 23 and 24 as shown in Figure 4 the connector plate becomes wedged or locked in position between adjoining sections 12 and 12a. The slight wedge taper of the inner surfaces of the end fins 23 and 24 complements the wedge taper of the slots in the connector plate so that once the connector plate is driven on it is not removable for practical purposes. As shown in the drawing in Figure 4 the tube 22 is also locked in position within the aligned notches 19 in the ns 16 by reason of the connector plate 25 lying closely against the outer periphery thereof. It is thus apparent that the connector plate performs the dual function of holding adjoining sections of the baseboard radiator together in locked integral relationship and further of holding and maintaining the tubing 20, 21, and 22 in position in close contact with the radiating fins 16.

It has previously been stated that the notches 17, 18, and 19 have their opposed walls tapered as shown at 30, 31, and 32. This taper facilitates the wedging of the conduit or tubing 20, 21, and 22 in the small circular end of each of the respective notches 17, 18, and 19 whereby there is eicient heat transfer between the conduit tubing 20, 21, and 22 and the spaced radiator fins 16. The tubing 20, 21, and 22 is preferably made of some good heat transfer metal such as copper or the like. The wedge lock of the connector plate 25 is made more certain in its wedging effect by reason of the tapered inner walls 36 and 37 of the end Walls 23 and 24. When the connector plate is driven into position on the sections the tapers of the connector plate are additive in their eifect with the tapered end walls 23 and 24 whereby there is guaranteed a wedge lock between the connector plate 2S and the abutting ends 23 and 24.

It will be readily apparent that in the use of baseboard radiators incorporating the principles of this invention any special heat installation job may be worked out merely by using a suicient number of the sections 12. The sections may be preassembled or assembled on the job site by rst laying in the necessary tubing 20, 21, and 22 along a plurality of sections making the desired length baseboard radiator and thereafter applying a connector plate 25 to each of the adjoining ends of the plurality of sections whereby the entire series of individual sections become an integral part of the entire unit baseboard radiator for any particular wall or room. As previously stated the connector plate performs the additional function of maintaining the tubing in locked position in the inner closed ends of the notches 17, 18, and 19 whereby when the radiator is in use there is good and ecient transfer by conductivity of the heat within the tube or conduit 21), 21, and 22 to the spaced ins 16 and also the end tins or Walls 23 and 24 of the several sections 12 making up the entire unit. The lightness of each unit 12 makes transportation of many of the sections of the baseboard radiator of this invention relatively easy and the assembly of a plurality of sections on the job site makes for relatively easy installation of heating systems incorporating baseboard radiators.

Numerous throughout a wide range without departing from the principles disclosed herein and I therefore do not dispose details of construction may be varied i limiting the patent granted hereon otherwise than as necessitated by the appended claims.
